2. Do tire rotation, didn’t have a quick and easy way to let ECU relearn new tire information.
3. When tire pressure indicator light ON, after the maintenance performed, the tire pressure needs to be reset to turn off the TPMS light.
4. Low tire pressure or leakage /replacement or installation of tire pressure monitoring equipment / tire replacement, sensor damage, etc. After those problems solved, TPMS needs to be reset.

Truly awesome tool, my tire sensors died out of battery and once it’s changed the dealer promised that the new ones will relearn, that never happened until I bought this tool and used it. Amazing tool, easy to use, all you need is a 9v battery and there are videos to help you.

These work perfectly for standard TPS sensors; but, wanted to use this to reset sensors placed on a Cargo Toy hauler. Sadly, no way to set these up for a second set of sensors beyond a cars primary 4. Would give it a 5 for standard TPS devices for a car but beyond that… didn’t work.

I bought my 2011 Impala new So I know these are the original OEM sensors. Don't start your car just put in the on position. Then hit both the lock and unlock buttons on the Key Fob and you will be in the Learning Mode. Then it takes about 20 seconds to reset all 4 tires. Just make sure you start the front Drivers side.

It is priced right. It works perfectly and quickly. My 2012 Chevy Equinox would not re-learn tire position when in re-learn mode. I tried 6 times to no avail. I ordered this, got it the next day, installed the 9v battery and put the Equinox in TPMS re-learn mode. 1st tire in 2 seconds, 2nd tire in 2 seconds all the way around until complete. It was that fast. Do not hesitate to buy this, IT WORKS!

This worked great. Had to find tire pressure screen on my dash. They all showed blank. Pushed and held button until reprogram screen came up. Scrolled to Yes and pushed button. Truck honked immediately. Started at front driver side and held device against tire truck honked again. Repeated around truck clockwise and once all four tires were done truck honked twice. Easy peasy. Well worth $17.

Each year when I change out my tires, I had to go back to the dealership to have the TPMS sensors recalibrated this tool does it for me at an excellent price and it works for my 2018 Enclave

Had purchased replacement TPMS sensors for our ‘15 GMC Acadia to be installed when our new tires were mounted. The tire shop installed the sensors when the tires were mounted but the tech said that they only had a “relearning tool” for the sensors that they sold. (I believe that they were punishing me for not buying their sensors!) when I realized that I needed the tool to reset the new sensors. I found this tool on Amazon. Good reviews, reasonable price and 2 day shipping (delay by Amazon turned it into 3 day but not a serious issue). The Acadia’s Owner’s Manual and the JDIAG Relearn Tool User Guide described the process which was pretty simple. Probably took less than 5 minutes. Tool will be used infrequently but will be useful after tire rotations since the tire shop won’t do it. I’m a satisfied customer!

This works, no issues with my 2024 GMC. Make sure the 9V battery is brand new. It didn't work to start with, the low battery light never came on but the TX did, nothing from the vehicle. Tried a new battery and it worked right away.

I was trying to avoid being overcharged by the auto shops to perform a very simple tire pressure monitoring system tire position re-learn, so when I saw this tool for $5, I thought what have I got to lose! Followed the included directions to a tee and the process could not have been quicker or smoother. I made sure by using my multimeter that the 9 volt battery (remember, battery is NOT included) I had was well over the 9 volt mark, as the instructions and other reviewers have indicated that it must be a new, fresh battery or the device won’t work. Pulled the car out of the garage and onto the driveway to avoid any radio frequency interferences, as is stated in the instruction manual. After placing my vehicle in the tire position re-learn mode, I started with the left front (driver’s side), then right front, followed by right rear and finally the left rear, each time touching the tool’s antenna onto each tire where the rim and tire meet, next to and parallel to each tire’s valve stem. Make sure to hold the white button on the tool down until you hear each tire make the horn blow indicating it has been accepted into the system. The entire procedure took less than 5 minutes. Well pleased!
